FEEDER FOR, BRIQUETTING PRESSES.

Application filed July 23, 1921.

This invention relates to mechanism for continuously feeding loose material in a hopper to the plunger of a l'niquetting press operating in the bottom thereof.

The general object of this invention 1s to provide a feeding mechanism capable of more efficiently feeding loose material to a briquetting press.

A more specific object of this .invention is to provide a feed mechanism capable of effectively agitating material in the hopper to prevent formation of arches.

A further object is to provide effective means for disintegrating such agglomerations of material as tend to obstruct or impede the flow.

A further object is to so construct and arrange the disintegrating devices that they will be effective to force the disintegrated material toward the bottom ofthe hopper.

A further object is to provide means for compacting the material in the bottom of the hopper beneath the feeding mechanism.

Other objects will be apparent on reading the following specification in connection with the drawings.

In the drawings, Figure 1 is a vertical sectional View taken transversely of the operating shaft and showing the feed elements in elevation.

Fig. 2 is a top plan view.

Fig. 3 isa vertical sectional view taken at therear ofthe feed mechanism.

ln the drawings is shown the preferred form of this invention. The hopper 1- is a feed hopper having inclined sides 2 at the upper end and a long` inclined side 3 along` which the material moves to bottom portion 4c. The side opposite the side 3 is par* tially open to accommodate the reciprocating feed members 6. Across the bottom of the hopper a reciprocating plunger 7 operates. The plunger carries the material out of the hopper into a mould 8 which is reciprocated by suitable mechanism upon a backing block 9.

The reciprocating' feeding members 6 are mounted upon two sets ofeccent-rics 10 and 11 offset 180 with respect to each other on the operating shaft 12. The shaft 12 is continuously driven through suitable gear ing 13 by motor 1li. The members 6 are mounted close together on the shaft 12 and have enlarged upper ends providing elon- Seral No. 482,090.

gated material engaging edge faces 15. which form a-ninterfingered reciprocating bar conveyor bed operating on the superposed ma terialin the hopper to continuously agitato it and conveyI it toward the wall 3. The longitudinal edge faces 1G of the feeding n'iembcrs are disposed above. and overlie the inclined wall 3 of the hopper throughouta substantial portion ofzits length. The faces 16 are serrated to obtain'better-feedingaction. The lower end of thef feeders areprov vided with vertical slots 17 through which pass a stationary rod 18.. By this arrange'- rnent'the lower ends of the feeders are con` fined to a substantially vertical up and down motion which causesthe. horizontal lower faces 19 thereof to tamp.. thematerial into a compact mass at the bottom of the hopper.

The confining of the'lower ends .of .the feeder bars to substantially a verticalmovement has the effect of increasing, the lateral throw of the upper ends of the feeder bars which renders the agitating and conveying action ofthe upper end of theffe-ederbars more effective, and causes the"` disintegration of the material toi-be .effect-cdas the inaterial entersbetween the side wall 3, and the upper ends ofv serrated edge faces 16v, theangular motion of thelbars tending: to crowd the material toward the bottom ofthe hopper and compact it therein.

- The :close spacing ofwthe4 fratreciproca ting memberscausesthem to eectually prevent the escape of material between them. How.- ever, any material working through between the feed members accumulates in the extension 20 at the rear of the hopper and is fed by the tamping ends 19 into the bottom of the hopper.

Furthermore, it is to be understood that the .particular forms of apparatus shown and described, and the particular procedure set forth, are presented for purposes of explanation and illustration and that various modifications of said apparatus and procedure can be made without departing from my invention as defined in the appended claims.

lhat I claim is:

1. In a feeder, a plurality of intertingering reciprocating bars, each of said bars having elongated angularly disposed longi tudinal and end edges, and means for actuating said bars to continuously move mate rial across the ends of the bars and longitudinally thereof.

2. ln a feeder, a material supporting sur face, a plurality of interlingering reciprorating` liars superposed over said surface and extendingl lono'itudinally thereof, said bars havingelongated end edges angular-ly disposed with respect to saiosi'irface, anrl means for actuating said bars to continuously move material across the ends of the bars towards said supporting surface and longitudinally of the supporting surface.

3. ln a feeder, a material supporting,` surface. a` plurality of interlingering reciproeating bars superposed over said sul fatte and extending longitudinally thereof, means for moving srid bars bodily toward and from and longitudinally with respeet to the supporting surface, said bars lisfivhip,` a greater amplitude of movement toward and from said surface at the receivingv end than at the discharge end.

Ll. ln a feeder, a feed hopper having an inclined wall, a plurality of interlingering reciprocating b: rs intermediate the top and bottom of the hopper, exteiiding longitudinally of the inclined wall and havi` elongated upper edes disposed at an inclination opposite to that of the said wall and means for moving said liars toward and` from said wall and longitudinally with respe-et thereto.

ln a feeder, a hopper having' an inclined wall, interingered reciprocating` bars supeposed over said inclined wall, a single drive shaft, staggered eccentrics thereon for actuating` said bars and means for restricting` the lower ends of the bars to substantially vertical up and down movement.

6. ln a feeder, a hopper, discharging means movable across the bottom of the hopper and means within the hopper operable to disintegrate the material, feed the disintegrated material toward the bottom 0f the hopper and to compact said disintegrated material in the bottom of the hopper.

ln a feeder, a material supporting surface, a series of interlingering reciprocating bars mounted upon staggered eccentrios, said 1oars each having one edge disposed above said supporting surface, said bars having also edges arranged to forni a snpporting` hed for material wiereby upon reciprocation of the bars said first mentioned edges operate to nieve material along the supporting surface and said second inentioned edges operate to move the material thereon toward said supporting surface.

8. ln a feeder for a. briquettingj press. a hfpper having a material supporting inclined wall, a plurality of intel. gering serrated, reciprocating bars overl` ing said invlineril wall, and extending lon ieudinally thereof, ineens for moving said bars bodily toward and from and longitudinally with espect to said wall.

9. a feeder a hopper7 discharging means i'iiovable across the bottom of the hopper and means within the hopper opersbl-e to move the material toward one Wall of the hopper and then downwardly to the bottom of the hopper, whereby the material disintegrated and con'ipacted in the bottom of the hopper.

l0. ln a feeder for a biiquettingl press, a hopper, a plunger movable through the hopper for pressingl the material to be briquetter, a plurality of members movable to cause such material to be carried toward one wall of the hopper and thence toward the plunger, said members having additional means to compact the material in front of the plunger, whereby the plunger, engages material partially con'ipacted.

ln testimony whereof, I hereunto aiiix my signature.
